Nature is amazing in so many ways. The natural state of how things evolve and develop sometimes leaves us stunned. Science is magnificent, as well.

The continued study of humankind in its pursuit for greater discoveries has helped make things easier and better for everyone. But when nature and Science combine, it leads to extraordinary results. Sometimes, they end up as great discoveries that will leave your mind blown.

It’s worth noting, too, that some of the most significant discoveries in Science came as an accident. Penicillin, Velcro, the microwave, vulcanized rubber, radiation, LSD, and even the first sign of the Big Bang – all these came to be by accident.

Here are 40 times when either Science or nature wowed us with its unique processes. Whether it’s natural growth or chemical composition, whether it’s discovered by accident or little home experiments from curious minds, this list will leave you with oooh’s and aaah’s one slide at a time.
